Well, I have a muffled bass when my music is playing, and from my research it seems as though I have the infamous Logic 7 amp blowing up concern.

Anyways,

I called my friend who is the service director at BMW of The Mainline, and he tells me they won't cover it under CPO.

I called a few other dealers as well and they all day it wouldn't be covered.

I saw a few people on here got it covered under their CPO. I called the dealership I bought it from and they are going to get back to me on what they can do for me if anything. I just bought the vehicle only 3 weeks ago, so I'm hoping they will.

However, with this being as big of a concern with the vehicle I'm assuming that even if I got it covered there would still be problems with it down the road anyway. I'm a bit of an audiophile and I like clean well sounding music, but the reliability here might be in question.What have other people done to correct or fix this.

Any advice as well on what I can do to try and get this covered? I hear some people have gotten estimates of $1,400.00.

There is a guy in the stickes who fixes them. He charges around $280 I think.. there is also a DIY from Paper in the DIY section to repair yourself.. I am sure that fix solves the issue so you would probably be good..

Sigh.... The L7 amp has been discussed so many times i can't even keep up anymore, did you search?? You cannot replace L7 with an aftermarket amp, email ilya, have him repair your amp for $320 it will come back more powerful than it was stock and he provides a warranty. Problem solved.

If you remove the L7 amp your navigation, phone, radio and pdc wont work, but if you wanna add an aftermarket amp to work alongside L7 you can do that, with the aftermarket amp you can power your floor subs, or even a box in the trunk, to easily connect that amp to your car you can get a harness from a member on here called Technic, which helps you get audio inputs from L7 into your aftermarket amp, so you dont have to cut any wires.

Yeah I want him to do mine too but I cant be without my hands free and navi I use my car for work.. Was hoping he could send me one and I could cross mail mine but I don't think he wants too.. considering doing my own..

I'd like to hear this too, anyone had problems after repair. The dealer I bought it from is still dragging their feet, but I'm assuming I'll have too seek another option down the road even if they do fix it as I bet it will blow up again
